1. We investigated the effects of short-term exposure to physiological levels of 17beta-estradiol and testosterone on vasocontractile responses in porcine coronary artery rings. 2. Concentration-response curves to endothelin-1, 5-hydroxytryptamine, the thromboxane analogue U46619 and KCl were constructed in endothelium-intact and endothelium-disrupted artery rings. 3. Thirty minutes exposure to 17beta-estradiol (1 and 30 nM) significantly attenuated vasoconstriction to endothelin-1, 5-hydroxytryptamine and U46619. Conversely, the same concentrations of testosterone significantly potentiated responses elicited by these contractile agents. These inhibitory effects of 17beta-estradiol and enhancing actions of testosterone on contractions were endothelium-independent. KCl-mediated contractions were unaffected by the presence of either sex hormones. 4. The oestrogen receptor antagonists, tamoxifen (10 microM) and ICI 182,780 (10 microM), were unable to reverse the inhibitory influence 1 nM 17beta-estradiol had on the agonist-mediated contractile responses. Similarly, the androgen receptor antagonists, flutamide (10 microM) and cyproterone acetate (10 microM), failed to affect the potentiating activities of 1 nM testosterone. The alteration in vasoconstrictive responses observed following acute exposure to either 1 nM 17beta-estradiol and 1 nM testosterone were apparent even in the presence of the protein synthesis inhibitor cycloheximide (10 microM) and the transcription inhibitor actinomycin D (10 microM). 6. In conclusion, we report a unique type of sex hormone action on the coronary vasculature. These events occur at low nanomolar concentrations of 17beta-estradiol and testosterone, are insensitive to conventional sex hormone receptor antagonists, are not blocked by de novo protein synthesis inhibitors and have rapid time-courses that are uncharacteristic of classical genomic activities.

Of the 915 men 901 were evaluated at a median followup of 18.5 months. The incidence of hot flashes was 30.1% and 74.3% in the polyestradiol phosphate and complete androgen ablation groups, respectively (p <0.001). In the polyestradiol phosphate group the frequency of and distress due to hot flashes were significantly lower than in the androgen ablation group. There was complete relief from hot flashes in 50% of the men on polyestradiol phosphate during followup compared with none on androgen ablation. The incidence of hot flashes did not differ in men with and without tumor progression.

Our purpose was to develop a new pharmacological approach for the treatment of prostate cancer (PCa), the most common neoplasia in men. Recently, we developed siRNA against the fusion oncogene TMPRSS2-ERG found in 50% of patients and showed an antitumoral activity in animal model. Herein, we want to compare or combine the developed siRNA to flutamide (FLU), one of the gold-standard treatment of PCa. Therefore, concomitant or subsequent association of FLU to siRNA TMPRSS2-ERG was performed in VCaP cells and in SCID mice bearing xenografted VCaP tumors. ERG, androgen receptor, cleaved-caspase-3 as well as phase 1 and 2 drug-metabolizing enzymes were investigated within tumors. We observed similar results in terms of TMPRSS2-ERG knock-down and cell viability impairment for all distinct schedules of administration. The association of siRNA TMPRSS2-ERG-squalene nanoparticles with flutamide displayed similar tumor growth inhibition as mice treated with siRNA TMPRSS2-ERG-squalene nanoparticles alone and was paralleled with modification of expression of ERG, androgen receptor, and cleaved-caspase-3. Phase 1 and 2 enzymes were essentially affected by FLU and reverted when combined with squalenoylated siRNA. In conclusion, these results confirm the therapeutic effectiveness of squalenoyl siRNA nanomedicine for PCa based on siRNA TMPRSS2-ERG.

In a previously conducted 2-year study, a concentration-dependent increase in Leydig cell adenomas was observed in Crl:CD BR(CD) rats fed diets containing the herbicide linuron. Linuron has been shown to be negative in a battery of six tests for genotoxicity; therefore, a nongenotoxic mechanism of tumorgenesis was investigated. Linuron is structurally related to the nonsteroidal antiandrogen, flutamide. Flutamide has also been shown to produce Leydig cell tumors within 1 year, presumably due to sustained hypersecretion of luteinizing hormone (LH) which occurs following disruption of the hypothalamic-pituitary-testicular (HPT) axis. To investigate whether linuron possesses antiandrogenic activity, sexually immature and mature CD rats were administered either 200 mg/kg linuron or 10 mg/kg flutamide (positive control) for 2 weeks. Accessory sex organs were weighed and serum hormone levels were measured to assess androgen status and alterations in the HPT axis. Serum from a multigeneration reproduction study with linuron was also analyzed for serum hormone levels. In addition, competitive receptor binding studies were conducted to evaluate the ability of linuron to bind to the androgen receptor. Linuron decreased accessory sex organ weights in sexually immature and mature linuron-treated rats. Increased serum estradiol and LH levels were observed in sexually mature linuron-treated rats. Serum estradiol and LH levels were also elevated in P1 and F1 male rats from the multigeneration reproduction study. These accessory sex organ and hormonal changes are consistent with those seen with the antiandrogen flutamide, the only exception being serum testosterone, which was elevated following exposure to flutamide but not to linuron. The inability of linuron to increase testosterone levels may reflect the lower potency of linuron as an antiandrogen compared with that of flutamide, which is a potent antiandrogen. Additionally, linuron competed with [3H]testosterone for binding to the androgen receptor. The IC50 data for competition to the androgen receptor suggest that linuron is approximately 3.5 times less potent than flutamide. These data are consistent with the effects seen with flutamide and demonstrate that linuron is a less potent antiandrogen than flutamide. Collectively, these data support the hypothesis that linuron produces Leydig cell tumors via an antiandrogenic mechanism where sustained hypersecretion of LH appears to be responsible for the development of Leydig cell hyperplasia and adenomas.

Flutamide, a nonsteroidal antiandrogen, was given to 11 men with prostate cancer, in doses of 750 to 1500 mg daily for 0.5--7 months. Four patients had a clinical remission and seven showed no response. All the patients showed a profound change in the peripheral metabolism of testosterone: markedly increased conversion to androsterone (A) and correspondingly decreased conversion to etiocholanolone (E); the A/E ratio rose to levels never before observed consistently in any group of healthy or diseased humans. This change was probably due to alteration by flutamide of the relative activities of steroid 5alpha and 5beta reductase in favor of the former. 24-Hour mean plasma testosterone was increased in five of the six patients studied for this parameter, for the group as a whole, testosterone rose from 279 ng/dl to 484 ng/dl (P less than .05). 24-Hour mean values for plasma dihydrotestosterone, dehydroisoandrosterone, LH and FSH showed no significant change, for the group as a whole, in the same six patients. Since flutamide did not change the metabolic clearance rate or volume of distribution of testosterone tracers, the increased plasma levels of the hormone were probably due to increased production.

To determine if and when short-term ablation of androgen action compromises the development of the male reproductive tract in mice, the androgen receptor antagonist hydroxyflutamide was administered orally to pregnant FVB/N mice and the reproductive tracts of the male offspring were examined when adult. Hydroxyflutamide (30 mg per day) for 5 days from day 11 to day 15 of gestation caused hypospadias in all male progeny. However, testis weights, seminal vesicle weights, and serum testosterone levels were not affected (p > 0.05) but caput-corpus epididymal weights were 15% lower than controls (p < 0.02). Shorter periods of treatment that included day 14 or 15 caused hypospadias, but treatments that did not include days 14 and 15 did not (p < 0.002). Hydroxyflutamide (30 mg, once or twice daily for 2 consecutive days) between days 15 and 20 of gestation demonstrated that androgen ablation on days 15 & 16 caused hypospadias, absence of prostate, and scrotal location of the seminal vesicles with abdominal testes (p < 0.05). Males exposed later in pregnancy had prostates, but the weights were reduced (p < 0.001); testes were scrotal and seminal vesicles were abdominal; caput-corpus epididymal weights were 15-30% lower than controls (p < 0.05), but the tubule contained large numbers of spermatozoa. Furthermore, testis weights, serum testosterone, and the response of the testis to a human chorionic gonadotropin (hCG) challenge in vitro were not compromised by hydroxyflutamide, and seminiferous tubules exhibited normal spermatogenesis. When males that had been exposed to hydroxyflutamide on days 13 & 14, 15 & 16, 17 & 18 and 19 & 20 were housed with sexually mature females, pregnancies resulted only from the day 19 & 20 treatment group. Thus, there are long-term effects caused by short-term blockade of androgen action at critical times during pregnancy and such effects could result in the inability to impregnate, irrespective of any externally visible indications of developmental anomalies.

In women and nonhuman primates, treatment with progesterone antagonists suppresses estrogen-dependent mitotic activity in the endometrial glands. This antiproliferative effect is paradoxical, because progesterone antagonists do not bind to the estrogen receptor (ER). While this phenomenon has been termed a "functional noncompetitive antiestrogenic effect," it does not occur in all species or in all regions of the primate reproductive tract, so is best referred to as an "endometrial antiproliferative effect." Recent studies of ours in both women and macaques revealed that the endometrial androgen receptor (AR) was increased by progesterone antagonist treatment. Because androgens are known to suppress estrogen-dependent endometrial proliferation, we hypothesized that the AR was involved in the antiproliferative effects induced by progesterone antagonists. In a test of this hypothesis, we administered the antiandrogen, flutamide, along with progesterone antagonists to ovariectomized, estrogen-treated macaques. Flutamide counteracted the suppressive effects of the progesterone antagonists on endometrial wet weight, thickness, stromal compaction, and mitotic index. Hyaline degeneration of the spiral arteries was also blocked by flutamide. These data implicate the AR as a functional component of the mechanism through which progesterone antagonists induce endometrial antiproliferative effects in the presence of estrogens.

Both morphologic analysis by annexin V/propidium iodide staining and TUNEL showed that physiologic T levels (1 to 10 nmol/L) induced a significant increase in apoptosis both in HK-2 cells and PTECs. In both types of cell lines pretreatment with the androgen receptor antagonist flutamide prevented the T-induced apoptosis. T-induced apoptosis was enhanced by treatment with cycloheximide and prevented by 17beta-estradiol. Fas, Fas ligand (FasL), and Fas-associating death domain containing protein (FADD) were clearly up-regulated within 48 hours of T treatment in HK-2 cells. Also, T significantly increased the expression of Bax protein (P < 0.01 vs. control) (an effect which was blocked by flutamide), and decreased the expression of Bcl-2. Western blot analysis showed that caspase-3 was activated. Moreover, cleavage into an 85-kD poly(ADP-ribose) polymerase-1 (PARP-1) terminal breakdown product was detectable. The changes in cellular morphology induced by T at 48 hours were no longer observed after the addition of caspase-8, caspase-9, and caspase-3 inhibitors to the culture medium.

We determined whether androgen deficiency induced by flutamide treatment during mid- and late pregnancy affects the functions of the porcine corpus luteum (CL). Pregnant gilts were injected with flutamide between days 43 and 49 (gestation day [GD] 50F), days 83 and 89 (GD90F), or days 101 and 107 (GD108F) of gestation. Antiandrogen treatment increased the luteal progesterone concentration in the GD50F group and decreased progesterone content in the GD90F and GD108F groups. Luteal levels of side-chain cleavage cytochrome P450 (CYP11A1) mRNA and protein were significantly downregulated in the GD90F and GD108F groups as compared with the respective controls. The 3β-hydroxysteroid dehydrogenase/Δ5-Δ4 isomerase (HSD3B) mRNA and protein expression were significantly reduced only in the GD108F group as compared with the control. Decreased luteal 20α-hydroxysteroid dehydrogenase (AKR1C1) mRNA and protein levels were observed in the GD50F group. Thus, androgen deficiency during pregnancy in pigs led to CL dysfunction that is marked by decreased progesterone production. Furthermore, exposure to flutamide during late pregnancy downregulated steroidogenic enzymes (CYP11A1 and HSD3B) in pigs. We conclude that androgens are important regulators of CL function during pregnancy.

Steroid hormones, which affect development of reproductive traits, alter immune responses in rodents and appear to control severity of disease in F1 hybrid NZB/W mice, an animal model of systemic lupus erythematosus. We tested the hypothesis that exposure of NZB/W fetuses to altered hormonal environments would influence subsequent expression of autoimmune renal disease and affect longevity. NZB females, pregnant with NZB/W fetuses, were treated from Days 13-18 of gestation with testosterone or the antiandrogen, flutamide. Similar treatments were carried out in C57BL/6 dams mated to DBA/2 males to permit comparison with nonautoimmune hybrid mice. Serum concentrations of testosterone were greater in testosterone-implanted dams of both strains, but concentrations of estradiol were greater only in C57BL/6 dams treated with flutamide. Alpha fetoprotein (AFP), which binds estrogen and modulates immune responsiveness, was greater in serum from both groups of testosterone-treated dams, while flutamide treatment increased serum AFP only in NZB dams. We conclude that factors governing circulating estradiol and AFP differed in pregnant NZB and C57BL/6 females. Morphological analyses confirmed effects of hormonal manipulation on the developing fetuses. Testosterone implants resulted in female offspring with greater anogenital spaces, and treatment of dams with flutamide eliminated the expected difference between anogenital spaces in females and males. Effects of altered prenatal hormonal environments on immune-mediated disease in NZB/W offspring were examined in a longevity study. Early deaths were delayed in NZB/W females produced by flutamide-treated dams. An unexpected result was observed in NZB/W males. Male offspring from both testosterone- and flutamide-treated mothers lived longer than males from control dams. This paradox suggested that a characteristic shared by both groups of treated NZB dams had similar effects on the developing fetuses. It is proposed that elevated concentrations of AFP modulated the course of autoimmune disease and contributed to increased longevity in NZB/W offspring of treated dams.

Patients diagnosed as having benign prostatic hyperplasia (BPH) had determination of prostate volume (PV), prostate-specific antigen (PSA), and serum testosterone before consideration for entry into a double-blind, randomized trial of flutamide (750 mg/day for 6 months). The mean PSA level for these patients (N = 43) was 7.6 ng/ml (range: 1.0 to 45.7), and the mean PV was 76.8 cm3 (range: 24 to 198). Linear regression analysis demonstrated a strong correlation between the two (r = 0.876, P less than 0.05). Every 10 cm3 of prostate volume accounted for 1.02 ng/ml of PSA in the serum. Twenty-two patients (11 treated with flutamide, 11 with a placebo) agreed to enter the study. Prostate volume decreased by 35% and PSA by 65% (P less than 0.001) within 6 months. These changes occurred despite a 58.3% increase in serum testosterone levels (P less than 0.01). Patients treated with a placebo experienced no significant changes. Side effects were minimal, and flutamide was well tolerated. These data suggest that androgen deprivation therapy with flutamide may be an effective and safe treatment for BPH.

In Radiation Therapy Oncology Group (RTOG) trial 92-02, after men received neoadjuvant hormone cytoreduction and radiotherapy for locally advanced prostate carcinoma, they were randomized to receive either 2 years of long-term androgen-deprivation (LTAD) or no further treatment (short-term androgen-deprivation [STAD]). The specific objective of the current study was to determine whether LTAD was a cost-effective treatment for patients with locally advanced prostate carcinoma.

To date, toxicological studies of endocrine disrupting chemicals (EDCs) have typically focused on single chemical exposures and associated effects. However, exposure to EDCs mixtures in the environment is common. Antiandrogens represent a group of EDCs, which draw increasing attention due to their resultant demasculinization and sexual disruption of aquatic organisms. Although there are a number of in vivo and in vitro studies investigating the combined effects of antiandrogen mixtures, these studies are mainly on selected model compounds such as flutamide, procymidone, and vinclozolin. The aim of the present study is to investigate the combined antiandrogenic effects of parabens, which are widely used antiandrogens in industrial and domestic commodities. A yeast-based human androgen receptor (hAR) assay (YAS) was applied to assess the antiandrogenic activities of n-propylparaben (nPrP), iso-propylparaben (iPrP), methylparaben (MeP), and 4-n-pentylphenol (PeP), as well as the binary mixtures of nPrP with each of the other three antiandrogens. All of the four compounds could exhibit antiandrogenic activity via the hAR. A linear interaction model was applied to quantitatively analyze the interaction between nPrP and each of the other three antiandrogens. The isoboles method was modified to show the variation of combined effects as the concentrations of mixed antiandrogens were changed. Graphs were constructed to show isoeffective curves of three binary mixtures based on the fitted linear interaction model and to evaluate the interaction of the mixed antiandrogens (synergism or antagonism). The combined effect of equimolar combinations of the three mixtures was also considered with the nonlinear isoboles method. The main effect parameters and interaction effect parameters in the linear interaction models of the three mixtures were different from zero. The results showed that any two antiandrogens in their binary mixtures tended to exert equal antiandrogenic activity in the linear concentration ranges. The antiandrogenicity of the binary mixture and the concentration of nPrP were fitted to a sigmoidal model if the concentrations of the other antiandrogens (iPrP, MeP, and PeP) in the mixture were lower than the AR saturation concentrations. Some concave isoboles above the additivity line appeared in all the three mixtures. There were some synergistic effects of the binary mixture of nPrP and MeP at low concentrations in the linear concentration ranges. Interesting, when the antiandrogens concentrations approached the saturation, the interaction between chemicals were antagonistic for all the three mixtures tested. When the toxicity of the three mixtures was assessed using nonlinear isoboles, only antagonism was observed for equimolar combinations of nPrP and iPrP as the concentrations were increased from the no-observed-effect-concentration (NOEC) to effective concentration of 80%. In addition, the interactions were changed from synergistic to antagonistic as effective concentrations were increased in the equimolar combinations of nPrP and MeP, as well as nPrP and PeP. The combined effects of three binary antiandrogens mixtures in the linear ranges were successfully evaluated by curve fitting and isoboles. The combined effects of specific binary mixtures varied depending on the concentrations of the chemicals in the mixtures. At low concentrations in the linear concentration ranges, there was synergistic interaction existing in the binary mixture of nPrP and MeP. The interaction tended to be antagonistic as the antiandrogens approached saturation concentrations in mixtures of nPrP with each of the other three antiandrogens. The synergistic interaction was also found in the equimolar combinations of nPrP and MeP, as well as nPrP and PeP, at low concentrations with another method of nonlinear isoboles. The mixture activities of binary antiandrogens had a tendency towards antagonism at high concentrations and synergism at low concentrations.

The records of 12 patients with SPCCE treated at the Division of Therapeutic Radiology during the period 1984 to 1998 were reviewed. The administered total radiation dosage ranged from 6 Gy to 32 Gy (average, 26.6 +/- 2.0 Gy). Two individuals underwent decompressive laminectomy and bilateral orchiectomy at the time of SPCCE and prostate cancer diagnoses. Ten patients had prior hormonal manipulative treatment (orchiectomy, estrogen, or Flutamide therapy).

For the treatment of cancer, the window between drug toxicity and suboptimal therapy is often narrow. Interindividual variation in drug metabolism therefore complicates therapy. Genetic polymorphisms in phase I and phase II enzymes may explain part of the observed interindividual variation in pharmacokinetics and pharmacodynamics of anticancer drugs. The cytochrome P450 superfamily is involved in many drug metabolizing reactions. Information on variant alleles for the different isoenzymes of this family, encoding proteins with decreased enzymatic activity, is rapidly growing. The ultimate goal of ongoing research on these enzymes would be to enable pharmacogenetic screening prior to anticancer therapy. At this moment, potential clinically relevant application of CYP450 pharmacogenetics for anticancer therapy may be found for CYP1A2 and flutamide, CYP2A6 and tegafur, CYP2B6 and cyclophosphamide, CYP2C8 and paclitaxel, CYP2D6 and tamoxifen, and CYP3A5. For this latter enzyme, the drugs of interest still need to be identified.

Leuprorelin (leuprolide acetate) is a synthetic analogue of gonadotrophin-releasing hormone (GnRH) [luteinising hormone-releasing hormone (LHRH)] which initially stimulates luteinising hormone (LH) and hence testicular androgen release; continuous administration then results in profound suppression of these hormones. Testosterone levels associated with castration are attained within 3 to 4 weeks. A biodegradable subcutaneous or intramuscular depot formulation of leuprorelin 3.75 or 7.5 mg, which releases the drug at a constant rate over 28 days, is available and may be preferred over daily subcutaneous injections. The progression of previously untreated advanced prostatic cancer is delayed in 70 to 90% of men receiving leuprorelin, with median survival of approximately 2 years. The efficacy of leuprorelin is equivalent to that of estrogen therapy, but the tolerability of the GnRH analogue is far better. In contrast to most other studies of GnRH agonists, a slight survival advantage has been reported for combined treatment with leuprorelin and the antiandrogen flutamide. Small noncomparative trials reveal that leuprorelin also causes regression of benign hyperplastic prostate tissue with corresponding relief of obstructive, but not irritative, symptoms although continuous treatment is necessary to maintain remission. Impotence and flushing occur in most leuprorelin recipients but, unlike diethylstilbestrol (stilboestrol), cardiovascular toxicity and gynaecomastia are not significant problems. Symptom flare, usually manifested as bone pain in buy eulexin prostate cancer patients and exacerbation of obstructive symptoms in those with benign prostatic hypertrophy, can occur in 4 to 29% at the beginning of treatment. Leuprorelin treatment is therefore an established effective palliative measure in men with previously untreated advanced prostatic cancer, and may have a role in those with benign hypertrophy who are unfit for surgery.

The present research was chiefly designed to determine the effect of the treatment of estrogenic agonist, estradiol benzoate (EB), or antiandrogenic compound, flutamide (Flu), at the weaning age on the expression of connexin (Cx) isoforms in the caudal epididymis of adult male rat. Animals buy eulexin were subcutaneously administrated with a single shot of either EB at a low-dose (0.015 µg of EB/kg body weight (BW)) or a high-dose (1.5 µg of EB/kg BW) or Flu at a low-dose (500 µg of EB/kg BW) or a high-dose (5 mg of EB/kg BW). Expressional changes of Cx isoforms in the adult caudal epididymis were examined by quantitative real-time PCR analysis. The treatment of a low-dose EB caused significant increases of Cx30.3, Cx31, Cx32, and Cx43 transcript levels but reduction of Cx31.1, Cx37, and Cx45 expression. Exposure to a high-dose EB resulted in very close responses observed in a low-dose EB treatment, except no significant expressional change of Cx37 and a significant induction of Cx40. Expression of all Cx isoforms, except Cx45, was significantly increased by a low-dose Flu treatment. Expressional increases of all Cx isoforms were detected by a high-dose Flu treatment. The current study demonstrates that a single exposure to estrogenic or antiandrogenic compound during the early postnatal developmental period is sufficient to disrupt normal expression of Cx isoforms in the adult caudal epididymis.

The nonsteroidal antiandrogenic drug flutamide [4'-nitro-3'-(trifluoromethyl)isobutyranilide] is a safe and generally well-tolerated drug used for the treatment of prostate cancer. We describe the case of a 74-year-old male who developed life-threatening acute liver failure during flutamide therapy. Other causes of acute liver failure were appropriately ruled out and there was no evidence of active prostate cancer or liver metastases. The use of the Naranjo probability scale indicated a highly probable relationship between the development of acute liver failure and flutamide therapy. Severe liver dysfunction has been rarely documented in patients treated with flutamide, even though cases of fulminant liver failure have been described. buy eulexin A few cases have been reported also among patients with hirsutism being treated with flutamide. The mechanisms responsible for the occurrence of hepatotoxicity during treatment with flutamide are unknown. Mitochondrial dysfunction seems to be implicated. The potential of flutamide to act as a potent hepatotoxin should be borne in mind when treatment with this drug is being planned.

LH receptor knockout (LhrKO) male mice exhibit a bilateral cryptorchidism resulting from a developmental defect in the gubernaculum during the inguinoscrotal phase of testis descent, which is corrected by testosterone replacement therapy (TRT). In vivo and in vitro experiments were conducted to investigate the roles of the androgen receptor (AR) and RXFP2 signals in regulation of gubernacular development in LhrKO animals. This study demonstrated that AR and RXFP2 proteins were expressed in the gubernaculum during the entire postnatal period. TRT normalized gubernacular RXFP2 protein levels inLhrKO mice. Organ and primary cell cultures of gubernacula showed that 5alpha-dihydrotestosterone (DHT) buy eulexin upregulated the expression of Rxfp2 which was abolished by the addition of an AR antagonist, flutamide. A single s.c. testosterone injection also led to a significant increase in Rxfp2 mRNA levels in a time-dependent fashion in LhrKO animals. DHT, natural and synthetic insulin-like peptide 3 (INSL3), or relaxin alone did not affect proliferation of gubernacular mesenchymal cells, while co-treatments of DHT with either INSL3 or relaxin resulted in an increase in cell proliferation, and they also enhanced the mesenchymal cell differentiation toward the myogenic pathway, which included a decrease in a mesenchymal cell marker, CD44 and the expression of troponin. These effects were attenuated by the addition of flutamide, siRNA-mediated Rxfp2 knockdown, or by an INSL3 antagonist. Co-administration of an INSL3 antagonist curtailed TRT-induced inguinoscrotal testis descent in LhrKO mice. Our findings indicate that the RXFP2 signaling pathway plays an important role in mediating androgen action to stimulate gubernaculum development during inguinoscrotal testis descent.

The expected mean cost was 32,564 dollars for LTAD compared with 33,039 dollars for STAD after accounting for the additional cost of salvage treatment for men who were treated with STAD. The mean number of quality-adjusted life years (QALYs) for men who received LTAD was 4.13 QALYs compared with a mean of 3.68 QALYs for men who received STAD. The cost-effectiveness acceptability curve analysis showed a 91% probability that LTAD was cost-effective compared with STAD. Although overall survival was similar in the LTAD and STAD groups, the patients buy eulexin who received LTAD experienced gains in QALYs and had lower costs, because LTAD prevented biochemical failure and the necessitating salvage hormone therapy.

The increased incidences of disorders of male reproductive tract as well as testicular and prostate cancers have been attributed to androgenic pollutants in the environment. Drinking water is one pathway of exposure through which humans can be exposed. In this study, both potencies of androgen receptor (AR) agonists and antagonists were determined in organic extracts of raw source water as well as finished water from waterworks, tap water, boiled buy eulexin water, and poured boiled water in eastern China. Ten of 13 samples of source water exhibited detectable AR antagonistic potencies with AR antagonist equivalents (Ant-AR-EQs) ranging from <15.3 (detection limit) to 140 μg flutamide/L. However, no AR agonistic activity was detected in any source water. All finished water from waterworks, tap water, boiled water, and poured boiled water exhibited neither AR agonistic nor antagonistic activity. Although potential risks are posed by source water, water treatment processes effectively removed AR antagonists. Boiling and pouring of water further removed these pollutants. Phthalate esters (PAEs) including diisobutyl phthalate (DIBP) and dibutyl phthalate (DBP) were identified as major contributors to AR antagonistic potencies in source waters. Metabolites of PAEs exhibited no AR antagonistic activity and did not increase potencies of PAEs when they coexist.

Intracellular amyloidbeta peptide (iAbeta1-42) accumulates in the Alzheimer's disease brain before plaque and tangle formation (Gouras et al., 2000) and is extremely toxic to human neurons (Zhang et al., 2002). Here, we investigated whether androgen and estrogen could prevent iAbeta1-4) toxicity, because both these hormones have a wide range of neuroprotective actions. At physiological concentrations, 17-beta-estradiol, testosterone, and methyl testosterone reduce iAbeta1-42-induced cell death by 50% in neurons treated after the injection and by 80-90% in neurons treated 1 hr before the injection. The neuroprotective action of the hormones is mediated by receptors, because the estrogen receptor (ER) antagonist tamoxifen and the androgen receptor (AR) antagonist flutamide completely block the estrogen- and androgen-mediated neuroprotection, respectively. Transcriptional activity is required for the neuroprotective action, because dominant negative forms of the receptors that block the transcriptional activity of the ER and AR prevent estrogen- and androgen-mediated neuroprotection. Proteomics followed by Western blot analyses identified increased levels of heat shock Avodart Medication Generic protein 70 (Hsp70) in testosterone- and estrogen-treated human neurons. Comicroinjection of Hsp70 with the iAbeta1-42 blocks the toxicity of iAbeta1-42. We conclude that estrogen and androgens protect human neurons against iAbeta1-42 toxicity by increasing the levels of Hsp70 in the neurons.

The Organisation for Economic Cooperation and Development (OECD) has completed phase 1 of the Hershberger validation intended to identify in vivo activity of suspected androgens and antiandrogens. Seventeen laboratories from 7 countries participated in phase 1, and results were collated and evaluated by the OECD with the support of an international committee of experts. Five androgen-responsive tissues (ventral prostate, paired seminal vesicles and coagulating glands, levator ani and bulbocavernosus muscles, glans penis, and paired Risperdal Dosing Cowper's or bulbourethral glands) were evaluated. The standardized protocols used selected doses of a reference androgen, testosterone propionate (TP), and an antiandrogen, flutamide (FLU). All laboratories successfully detected TP-stimulated increases in androgen-responsive tissue weight and decreases in TP-stimulated tissue weights when FLU was co-administered. The standardized protocols performed well under a variety of conditions (e.g., strain, diet, housing protocol, bedding). There was good agreement among laboratories with regard to the TP doses inducing significant increases in tissue weights and the FLU doses decreasing TP-stimulated tissue weights. Several additional procedures (e.g., weighing of the dorsolateral prostate and fixation of tissues before weighing) and serum component measurements (e.g., luteinizing hormone) were also included by some laboratories to assess their potential utility. The results indicated that the OECD Hershberger protocol was robust, reproducible, and transferable across laboratories. Based on this phase 1 validation study, the protocols have been refined, and the next phase of the OECD validation program will test the protocol with selected doses of weak androgen agonists, androgen antagonists, a 5alpha-reductase inhibitor, and chemicals having no androgenic activity.

Human arylacetamide deacetylase (AADAC) can hydrolyze clinical drugs such as flutamide, phenacetin, and rifamycins. AADAC is a glycoprotein, but the role of glycosylation remains unclear. In the present study, we investigated the effect of glycosylation on AADAC enzyme activity. Immunoblot analysis of mutant AADACs that contained an asparagine (N, Asn) to glutamine (Q, Gln) substitution at either residue 78 or 282 (N78Q or N282Q) showed a different migration compared with the wild-type protein. A mutant AADAC that contained N to Q substitutions at both residue 78 and 282 (N78Q/N282Q) showed a similar migration to AADAC in human liver microsomes (HLM) treated with endoglycosidase H (Endo H), which produces deglycosylated proteins. This result indicated that AADAC was glycosylated at both N78 and N282. Mutant types of AADAC with the Suprax Tablet Uses N282Q and the N78Q/N282Q substitutions showed dramatically lower phenacetin hydrolase activity than did the wild-type protein. The treatment of wild-type AADAC-expressing HuH-7 cells with tunicamycin, which produces unglycosylated protein, decreased AADAC enzyme activity. However, the treatment of the HLM with Endo H caused no decrease of AADAC activity. Thus, the oligosaccharide chain, per se, was not important for AADAC activity in the mature form. The mutant types of AADAC containing the N282Q and the N78Q/N282Q substitutions were not detected by immunoblotting analysis after non-reducing SDS-PAGE, suggesting that the glycosylation of AADAC at N282 was important for proper protein folding. Overall, this study found that the translational, but not post-translational, N-glycosylation of AADAC plays a crucial role in regulating AADAC enzyme activity.

Progression of castration-resistant tumors is frequent in prostate cancer. Current systemic treatments for castration-resistant prostate cancer only produce modest increases in survival time and self-renewing Tumor-Initiating Cells (TICs) are suspected to play an important role in resistance to these treatments. However it remains unclear whether the same TICs display both chemo-resistance and self-renewing abilities throughout progression from early stage lesions to late, castration resistant tumors. Here, we found that treatment of mice bearing LNCaP-derived xenograft tumors with cytotoxic (docetaxel) and anti-androgen (flutamide) compounds enriched for cells that express TROP2, a putative TIC marker. Consistent with a tumor-initiating role, TROP2high cells from androgen-sensitive prostate cancer cell lines displayed an enhanced ability to re-grow in culture following treatment with taxane-based chemotherapy with or without androgen blockade. TROP2 down-regulation in these cells reduced their ability to recur after treatment with docetaxel, in the presence or absence of flutamide. Accordingly, in silico analysis of published clinical data revealed that prostate cancer patients with poor prognosis exhibit significantly elevated TROP2 expression level compared to low-risk patients, particularly in the case of patients diagnosed with early stage tumors. In contrast, in androgen-independent prostate cancer cell lines, TROP2high cells did not exhibit a differential treatment response but were characterized by their high self-renewal ability. Based on these findings we propose that high TROP2 expression identifies distinct cell sub-populations in androgen-sensitive and androgen-independent prostate tumors and that it may be a predictive biomarker for prostate cancer treatment response in androgen-sensitive tumors.
